Abstract

There is disclosed a method and apparatus adapted for securing computing process running on a computing hardware node in a grid computing system through the formation of virtual trusted node. Grid computing breaks up a computational task into a smaller computation sub-tasks. These sub-tasks are distributed to many computers where once executed, the results are returned to a centralized node for compilation. Data integrity and security becomes are of paramount concern. The proposed invention solve such a concern by providing a method of creating a virtual trusted node in a grid computing system through the creation of wrapped-task (11, 21) by wrapping a software for the sub-tasks together with an operating system (12, 22), sending the wrapped-task to the computer (40) in the grid computing system and executing the wrapped- task by way of a virtual machine monitor (30) and a trusted platform module (41). The operating system is provided with only the minimum and necessary functions to execute the wrapped-task. A computer apparatus (40) for creating such virtual trusted node is also disclosed.
